The McDonnell-Douglas (Boeing) AH-64 helicopter was selected as the winner in the competition with Bell's YAH-63 in December 1976. The name Apache stuck to the helicopter in 1981. This highly efficient machine features four-blade rotors powered by two General Electric T700-701 turbine engines with a capacity of 1696 horsepower. The residual wings are equipped with conventional trailing edge flaps, and the tail plate enhances the longitudinal rudder. The two-person crew takes positions one after the other in the armored cabin. The pilot's seat is at the back, and the weapon operator/gunner is in front. The key to the helicopter's universal use is the TADS systems at the gunner's base and the PNVS systems used by the pilot. TADS is a set of laser designator and rangefinder for target tracking and a forward-looking infrared sensor that duplicates normal optics. The PNVS system is an advanced FLIR system that allows you to pilot a helicopter just above the ground to prevent or delay detection by enemy anti-aircraft defenses. Apache helicopters participated in the operation in Panama in 1989, during the Desert Storm in 1991, and the latest conflict in Iraq (2003). In the late 1990s, the construction of a new version of the helicopter began, equipped with a Martin/Westinghouse Longbow millimeter radar installed above the head for weapon control. It is used to control Rockwell AGM-114 Hellfire anti-tank missiles. Technical data: Final speed: 300 km/h; climb speed 12.7 m/s, maximum range (without external tanks): 689 km, armament: 30mm Hughes M230A1 Chain Gun fixed-1 cannon, and external armaments - most often Hellfire missiles.
